Okay guys, I am new to C and I am a trying to construct a 2D array that will hold a BMP image and be able to edit the RGB values. I haven't been able to find anything online about how to access the RGB values or how to put this image in the 2D array and I am really stuck as to where to start. HELP!!!!
See the reference Writing BMP image in pure c/c++ without other libraries of Ed Heal. Things to note:
Define the structures. Don't use arrays of unsigned chars to make the headers as in the referenced post.
Both in reading and writing, take care to fill the scanlines. They must be a multiple of four, so the last bytes may not be pixels and contain garbage.
See also my earlier post What is wrong with this code for writing grey-scale bmp from an image RGB bmp pure C - Windows OS which contains the headers and can serve as a partial example.
